WINDOW-SASH FASTENER.

Specicaton of Letters Patent.

Patented May 24, 1910.

Application led December 11, 1909. Serial No. 532,648.

To all whom it may concern:

Be it known that I, HARRY KELLEM, a citizen of the United States,residing at Rineyville, in the county of Hardin and State of Kentucky,have invented certain new and useful Improvements in Window- SashFasteners, of which the following is a specification, reference beinghad to the accompanying drawings.

This invention relates to certain new and useful improvements in sashfasteners and has for its object to provide a very simple device whichwill securely hold the sashes in the frame against movement so that anydesired amount of ventilation may be secured.

Another object is to provide a movable sash engaging member mounted uponthe top rail of the lower sash at one side thereof, said member beingactuated by an eccentric to move the same into binding engagement withthe side rail of the upper sash, whereby the sashes may be lockedagainst movement with relation to each other.

With these and other objects in view, the invention consists of thenovel construction, combination and arrangement of parts, hereinafterfully described and claimed, and illustrated in the accompanyingdrawings, in which Figure 1 is a vertical section through the sashespositioned in the window frame, showing my improved :fastener inoperative position; Fig. 2 is a perspective view of the fastener securedupon the sashl rail; Fig. 3 is an enlarged vertical section throughtherail of the sash and the fasteners; Fig. 4 1s a detail perspective viewof the attaching plate, and Fig. 5 is a similar view of the movablebearing member.

Referring to the drawings, 5 indicates the window-frame in which theupper and lower sashes 6 are vertically movable. The sashes have theirvertical edges disposed in the guide grooves 7.

My improved fastener is mounted upon the top rail of the lower sash atone side of the same and comprises the attaching plate 8 which is formedwith the central longi tudinal recess 9. This plate has its inner endflanged as shown at 10, said flange being disposed inwardly at an angleand adapted to bear against the outwardly inclined edge 6 of the sash. Abar 11 extends over the recess 9 and connects the separated portions ofthe plate. This bar is disposed above the plane of the plate for apurpose which will hereinafter appear. A bearing member 12 is formedwith a longitudinally extending portion 13 which is adapted to bedisposed upon the attaching plate 8 and is provided with a slot 14through which a pivot pin 15 extends. The outer portion of this bearingmember is disposed below the plane of the portion 13, as shown at 16,and is adapted to move in the recessed portion 9 of the plate 8. The bar11 retains this bearing member in the recess at all times and preventsits vertical movement. A disk 17 is eccentrically pivoted upon the pin15 and upon the longitudinally extending portion 13 of the bearingmember. The bearing member, however, has free longitudinal slidingmovement'between this disk and the surface of the attaching plate. Thedisk 17 is also formed with a handle portion 18 by means of which thesame may be conveniently manipulated. The periphery of this disk isadapted to contact with the inner surface of the outer vertical flangeof the U-shaped portion 16 of the bearing member, and when the disk 17is turned upon its pivot 15 the eccentric action thereof will force thebearing member outwardly and bind the same upon the vertical side railof the upper sash.

In order to provide a more effectual bindl ing action or frictionalengagement of the bearing member with the rail sash, I preferably secureupon the outer face of the bearing flange by means of a suitableadhesive material a hard rubber covering 19, and it will be obvious thatwhen this bearing member is forced into engagement with the sash rail,that the sashes will be forced apart and frictionally held in thegrooves 7 of the frame by means of the engagement of this rubber plate19 with the sash frame which will absolutely prevent any slidingmovement of the sashes with relation to each other. In this manner thesashes may be raised and lowered to provide sutlicient ventilation fromthe top and bottom of the window, and the eccentric disk 17 manipulatedto hold the bearing member 12 in engagement with the rail of the uppersash. The sashes will be held in their relative positions againstaccidental release, or indeed against any movement whatever until theeccentric disk 17 is turned to release the bearing member from contactwith the sash. This vdevice will also obviate the liability of intrudersentering the apartment, as the proper ventilation may be obtained bypositioning the sashes, and the sashes then securely looked againstmovement, the movement of the vsashes by means .of manual force beingimpossible until the eccentric locking disk:

is released.

From the foregoing it will be seen that I have provided a sash fastenerof comparatively si-mple construction and one `which is very effectiveand efficient in its operation. The sashes may be instantly loclred inany desired position.

A sash fastener constructed as above set forth may be inexpensivelyproduced and readily secured in operative position without requiring anymaterial yalteration in the sash. As no delicately constructed elementsare employed it -Will be obvious that the device is also very durableand is not liable to become inoperative from long continued use.

While I have shown and described what I believe to be the referredembodiment of the invention, it will be obvious that numerous minormodifications may be resorted to without departing from the spirit orsacriicing any of the advantages of the invention.

ing a longitudinal recess, a bearing member slidable on said attachingplate having a slotted longitudinally extending portion and a flange onits outer vend, a pivot pin secured in the Aattaching plate extendingthrough lsaid slot, the outer end of said bearing member being disposedbelow the plane'of the slotted portion and movable in the recess in saidplate, a bar integrally formed with the plate extendin over said bearingmember, a dslr eccentrica` ly pivoted on said pivot pin, the peripheryof said disk engaging with the flanve of said bearing member, and arubber acing plate secured to said .flange adapted to be held in lockingfrictional engagement with the rail of the upper sash.

In testimony whereof I hereunto aix my signature in the presence of twoWitnesses.
